TLC7725IDG4

PMIC - Supervisors

The TLC7725IDG4 is an integrated circuit (IC) designed to provide a voltage supervisor solution to motherboards, mobile devices, and peripherals. This IC is ideal for applications that require a longer battery life, protection from overvoltage conditions, and efficient operation from low to high voltages. It is particularly suitable for applications in the automotive, telecoms, and consumer electronics industries.

The TLC7725IDG4 utilizes a secure-transient level of voltage regulation, built with a power-failure monitor that is designed to monitor the main power supply and detect fault conditions in it. In case of an overvoltage or undervoltage fault, the IC is designed to take appropriate corrective action. This corrective action prevents any further damage to the system and recovers the system quickly by re-energizing itself.

The working principle of the TLC7725IDG4 IC is based on open-drain circuits. It has an output control register (OCR) to control the outputs, and it also has multiple power supplies for flexibility. The OCR stores the output voltage thresholds for each channel. In other words, it determines the voltage levels at which each output turns “on” and “off”.

The IC also has several protection features, including circuit protection, power supply undervoltage protection, blank check pulse prevention, brown-out protection, active converter fault detection, and power failure detection. These features provide robust protection against various types of damages, such as short-circuits and electrical over-stresses.

The IC offers a wide range of operating temperature ranges, and is designed to work over a wide voltage range as well. Its package is designed to allow easy mounting in dense environments, and is also provided with an optional heat sink to improve thermal dissipation.

The TLC7725IDG4 is an ideal voltage supervisor IC that provides reliable, efficient, and flexible operation in various applications. It is especially suitable for applications where multiple channels need to be monitored simultaneously and power supplies or system components need to be protected against various types of fault conditions.
